Antishock and Vibration Lenses

Photonics Spectra
Aug 2018The HF-12M and HF-5M series of Fujinon "anti-shock & vibration" lenses from Framos Technologies Inc. are designed for robotics and industrial applications.

The Fujinon design has been tested under 10-G and sine wave vibration at up to 500 Hz and 100 m/s² and is particularly suitable for applications in robotics and in high-vibration environments. As a result, the optical axis of a conventional lens shifts by up to 26 µm, which is equivalent to about 7 pixels for second-generation Sony Pregius sensors. Measured by contrast charts, as the resolution decreases dramatically, the lenses will become useless. For developers of mechanically stressed imaging systems, it is important to pay particular attention to the robustness against shocks and vibrations.

Fujinon's antishock and antivibration design is based on a patented elastic fixation of the internal lens arrangement, which not only provides long-term protection against shocks and vibrations but also works well with changes in humidity and temperature. The optical axis shifts only by 4 to a maximum of 10 μm, dependency on adhesives is minimized, and a long-term stable performance and consistently good image quality is guaranteed.More products
